WebThis theory states that there are seven major tectonic plates in the world today and fourteen/twenty-two smaller tectonic plates. The Pacific Plate is different because it is entirely under the sea. Tectonic plates come in many shapes. Continental tectonic plates are made of granite (light) and oceanic tectonic plates are made of basalt (heavier). WebSeismic Gap Theory Theory that states sections along a fault that have been inactive have the greatest potential for an earthquake in the near future. Monitoring Recursory Phenomena Changes that occur in the environment (tilted rock structures, changes in water table, etc.) that may indicate an oncoming quake.

WebA seismograph is an instrument that measures and registers seismic waves that travel through the Earth as the outcome of an earthquake. The terms seismograph and seismometer are often used correspondingly; however, unlike the Seismograph, seismometer doesn’t possess the capacity to record the phenomena. WebSeismic Gap Theory.

WebThe seismic gap or seismic cycle hypothesis has been, and appears still to be, applied to California for predicting seismic hazard (see, for example, WGCEP, 2002). One cannot test the seismic cycle model in a region (e.g., California) because relevant earthquakes occur too infrequently. But the seismic gap hypothesis of McCann et al. [1979] and ...
